Young kangaroos who spend more time alone with their mothers have a higher chance of surviving in the wild. They also tend to be larger and heavier than their peers when they spend more time with their mother, according to a recent study published in Springer's journal Behavioral Ecology and Sociobiology.
A study found that male birds' mobbing behavior, such as dive bombing and aerial swoops, serves not only as protection against predators but also as a way to showcase their physical qualities to attract females. When females from the same species are present, males increase their participation in these displays.
A team of researchers discovered that the tiny yellow-striped Amazonian frog has a special skin chemical that allows it to live comfortably among leaf-cutting ants. The frogs' skin extracts mimic the ants' own chemical signals, preventing attacks and enabling coexistence.
Researchers found that men prefer masculine men as allies in a physical fight but feminine-looking women in emotional support, while women's preferences are the opposite. This suggests an evolutionary basis for these differences, with alliances benefiting ancestral males and improving their social rank.
Researchers found that deer tend to flee away from observers, with a strong preference for escaping north- or southwards. This behavior is thought to be due to the deer's magnetosensitivity, allowing them to coordinate their escape plans and maintain group cohesion.
Researchers manipulated video footage to study male jumping spiders' behavior, finding that size assessment influences their decision-making. Larger spiders are less likely to approach smaller opponents, while smaller spiders can't scare away larger opponents.
Male fiddler crabs use deception to their favour by blurring the line between original and regrown claws. They adapt their combat strategies based on claw strength, opting for smaller opponents with weakened regrown claws to avoid injury.
Researchers found that fish from different species associate with each other when they share the same food, suggesting a role for chemical cues in group bonding. This study suggests that shared dietary preferences may be a key factor in promoting social learning and information transfer among fish.
Researchers found that processus length is crucial during mating for seed bugs, particularly when a rival male is present, and bigger isn't always better. Males with medium-length processus are most likely to fertilise female eggs successfully.
Penguin parents' fixed division of labor makes them vulnerable to climate change, as they cannot adapt to food shortages. Sharing roles could provide up to 34.5% more feeds for chicks, but it's a complex strategy due to the smaller, less aggressive females' limitations.
Researchers observed a female orangutan being killed by another female, with a male recruited as a hired gun. Female-female aggression is rare, and the case defies typical patterns of joint coalitional killings.
Research found that cheek-padded males are significantly more successful in fathering offspring, with dominant males having greater reproductive success during their tenure as dominant. However, other males were able to sire offspring during periods of rank instability or at the beginning and end of a dominant male's reign.
A study by Denson McLain found that larger male soldier beetles exhibit a size-related preference for large females, resulting in stronger assortative mating. This preference increases their likelihood of encountering and mating with more fecund females.
Researchers found that crow chicks raised alongside a cuckoo chick begged less intensely than those in nests without any unrelated broods present. Despite this, the young crows ultimately grew bigger than the cuckoos. The study suggests that sharing the nest with a cuckoo may be advantageous for crow chicks.
Flocking behavior of European starlings is studied in a computational model called Star Display. Researchers found that agitation waves form when individuals repeat the fear reaction or escape maneuver of a close neighbor.

Research reveals Norwegian lemmings use aposematism to signal their defensiveness through warning calls and conspicuous coloration. This strategy helps reduce the risk of becoming prey, making their long-distance movements more conspicuous.
Researchers tracked female black-tailed deer's movements and found their home ranges were very small, averaging 0.74 square kilometers, with core areas of just 0.08 km². This site familiarity helps them survive by knowing the best foraging spots and avoiding risky territories.
A study found that female great tit birds excel in spatial and learning abilities compared to males. This cognitive superiority may be linked to their lower social standing and increased need for food pilfering, allowing them to supplement their limited food supply.
Research shows that fruit fly females combine personal preferences with social information when choosing egg-laying sites. While most follow the group's cue, some females ignore social influence and stick to their own preference. This complex decision-making process is influenced by environment, genetics, and social context.
White-footed sportive lemurs use scent-marks in latrines to maintain contact with family members and inform intruders of a male's presence. The study found that males visited latrines more often during nights when an intruder invaded the territory, promoting social bonding among group members.
A study of wild East African chimpanzees found that females with high levels of male competition experience lower C-peptide levels, indicating energy deficit and potential weight loss. This can negatively affect their reproductive ability and fertility rates.
Male dwarf spiders use mating plugs made of a liquid material that hardens over time to block access to the female's sperm storage organ. Small plugs are less effective than large ones, but both size and age play important roles in their efficacy.
